/* Define an ELF note identifying the operating-system ABI that the
   executable was created for.  The ELF note information identifies a
   particular OS or coordinated development effort within which the
   ELF header's e_machine value plus (for dynamically linked programs)
   the PT_INTERP dynamic linker name and DT_NEEDED shared library
   names fully identify the runtime environment required by an
   executable.

   The general format of ELF notes is as follows.
   Offsets and lengths are bytes or (parenthetical references) to the
   values in other fields.

offset	length	contents
0	4	length of name
4	4	length of data
8	4	note type
12	(0)	vendor name
		- null-terminated ASCII string, padded to 4-byte alignment
12+(0)	(4)	note data,

   The GNU project and cooperating development efforts (including the
   Linux community) use note type 1 and a vendor name string of "GNU"
   for a note descriptor that indicates ABI requirements.  The note data
   is four 32-bit words.  The first of these is an operating system
   number (0=Linux, 1=Hurd, 2=Solaris, ...) and the remaining three
   identify the earliest release of that OS that supports this ABI.
   See abi-tags (top level) for details. */
